Hillary Scott of country super group Lady Antebellum will join Adam Levine on Season 4 of “The Voice” as a guest mentor, Access Hollywood can exclusively reveal!

Both Adam and Hillary are thrilled to be working alongside one another as the pair searches for the music world’s next “Voice” on the NBC reality hit!

“I was so happy that Hillary was interested in coming on ‘The Voice’ to mentor my team,” Adam told Access. “Maroon 5 and I recorded a song with her for our last studio album and we had a great time collaborating in the studio.”

Adding, “She is an incredible performer and artist. I know my team will be able to learn a lot from her.”

Hillary – who married drummer Chris Tyrrell in January 2012 and is expecting a baby this summer – is also looking forward to work with Adam again.

“I was so excited to join Adam for a couple days on ‘The Voice,’” the “Just A Kiss” singer told Access. “It’s an honor to mentor his team… he’s going to have some tough choices to make!”

And the expectant mom even threw a friendly barb at fellow country superstar (and “Voice” coach) Blake Shelton, adding, “I’m sure [we’ll have] way more fun than Blake’s team!”
